PLANT IOIZ COOLING HOT COKE AND UTILIZING THE H EAT LIBEBA'IID Tm!- Application filed January 19, 1922. Serial No. 580,487.

To all whom it may concern:

Be it known'that I, AnNoLn Monmm, a citizen of Switzerland, residing at and whose post-oilice address is Oberwmterthur, Romerstrasse 21, Switzerland, have invented certain new and useful Improvements 1n Plant for Cooling Hot Coke and Utilizing the Heat Liberated Thereby, of which the following is a specification.

The invention relates to a plant for dry cooling of coke by means of cooling gases conducted in a closed circuit through the coke and over a heat exchanging device. It is based on the factthat the plant consists of at least two coke cooling chambers and of at least two heat exchanging devices that are connected with each other by means of cool gas conduits'that can be closed, that each cooling chamber, instead of being 1nseparably connected with only one heat exchanging device can be selectively connected with at least two heat exchanging devices, or that each heat exchanging device can be selectively connected with at least two coke cooling chambers, in order not to be obliged to suspend the operations of the heat exchanging device when the operatlon of a coke cooling chamber is suspended, or to suspend the operation of the coke cooling chamber when the operation of a heat exchanging device is suspended.

One form of the invention is illustrated in the drawin in which Fi 1 is a p an view of a plant embodying t e invention;

Fig. 2 is a section on the line 22 of Fi 1, drawn on an enlarged scale;

Figs. 3 to 9 are detail sectional views of the switching devices shown in difierent positions.

a is a coke oven battery in which the hot coke is formed, 6 a coke cooling plantconsisting of the coke cooling chambers c, and the boilers e in which cooling plant the coke is cooled in a well known manner by means of an inert gaseous medium, the medium being circulated by means of the blowers it through the conduits 1' in a circular path through the mass of coke in the coke chambers and through the chambers of the boilers.

The hot coke is introduced into the cooling chambers by means of the portable rebe discharged from the cooling chamber. It is then received by railroad cars Z waiting for it on which it is carried to its destination.

The cooling as conduits r are provided with reversing evices s and connecting conduits t that can be shut off. In this manner it is made possible to connect, for example, in the event of a suspension of the operation of one of the cooling chambers or of a boiler, the boiler or the cooling chamber originally coo erating with the same, with another coo ing chamber or boiler, instead of disconnecting them also. In the position of the reversing devices 8 shown in Fig. 3, each of two cooling chambers is connected with the opposite boiler. In the position shown in Fig. 4:, the upper cooling. chamber and in Fig. 5 the lower cooling chamber is disconnected. At the same time both boilers are connected with the cooling chamber which is still in operation. In igs. 6 and 7 positions are shown in which both cooling chambers are workin with the upper, and lower boilers respectively. In Fig. 8, the upper cooling chamber is working in conjunction with the lower boiler, whereas the lower cooling chamber and the upper boiler are disconnected. Fig. 9 represents the osition in which the lower cooling cham or is connected with the up er boiler, whereas the upper cooling cham er and the lower boiler are disconnected. The reversing is done by revolving the device a which are three-way valves by means of the hand wheels to.

I claim:

1. A plant for dry cooling hot coke comprising at least two coke cooling chambers, at least two heat exchanging devices, means for circulating cooling gases in a closed circuit through each cooling chamber and the corresponding heat exchanging device, and means whereby each coolin chamber may be selectively connected wit any or all of at least two heat exchanging devices and each heat exchanging device may be selectively connected with at least two coolin chambers, said means maintaining a closed circuit between the interconnected cooling chambers and heat exchanging devices.

2. A plant for dry cooling hot coke comprising at least two coke cooling chambers, at least two heat exchanging devices, means for circulatin 1 in a closed circuit throng each coo g chamber and the corresponding heat exchanging device, a closed circuit between the interconnected and means whereby each cooling chamber cooling chambers and heat exchanging demay be connected with at least one nonvices.

corresponding heat exchanging device and In testimony whereof I have aifixed my each heat exchanging device may be eonsignature.

nected with at least one non-corresponding coo1ingchamb'er,"said means maintaining ARNOLD MOETTELI.
